DWT-DCT-SVD and LWT-SVD functions are missing

[kamredudhamsingh]

These functions are missing can you provide them?

[Saeid-jhn]

Thanks for your notification. I added the algorithm: DWT-SVD. The mentioned functions are not implemented yet. It is prepared as an empty template so it can be easy to extend and contribute by everyone.

Following error pops up on using DWT-SVD method,

Matrix dimensions must agree.

Error in dwt_svd (line 21)
HSw_hat = HSw + alpha.*Sw;

Error in watermark (line 9)
[watermarked_image, extracted_watermark] = dwt_svd(cover_image,watermark_logo,alpha,attack,param);

Error in main (line 101)
[watermarked_image, extracted_watermark] = watermark(cover_image,watermark_logoi,method,alpha,attack,param);

How to resolve this.

使用DWT-SVD方法时弹出以下错误，

矩阵尺寸必须一致。

dwt_svd中的错误（第 21 行）HSw_hat = HSw + alpha.*Sw;

水印错误（第 9 行）[watermarked_image， extracted_watermark] = dwt_svd（cover_image，watermark_logo，alpha，攻击，参数）;

主错误（第 101 行）[watermarked_image， extracted_watermark] = 水印（cover_image，watermark_logoi，方法，alpha，攻击，参数）;

如何解决这个问题。

hello,have you solved this problem.
